Spontaneous rotating vortex lattices in a pumped decaying condensate.
TLDR
This work model trapped, pumped, decaying condensates by a complex Gross-Pitaevskii equation and analyzes the density and currents in the steady state.
Pade approximations of solitary wave solutions of the Gross-Pitaevskii equation
Pade approximants are used to find approximate vortex solutions of any wind- ing number in the context of Gross-Pitaevskii equation for a uniform condensate and condensates with axisymmetric trapping
Motions in a bose condensate: VI. Vortices in a nonlocal model
Nonlocal nonlinear Schrodinger equations are considered as models of liquid helium II. The models contain a nonlocal interaction potential that leads to a phonon-roton-like dispersion relation. Also,
SOLITARY AND PERIODIC SOLUTIONS OF NONLINEAR NONINTEGRABLE EQUATIONS
The singular manifold method and partial fraction decomposition allow one to find some special solutions of nonintegrable partial differential equations (PDE) in the form of solitary waves, traveling
Scenario of strongly nonequilibrated Bose-Einstein condensation

Nonlocal Nonlinear Schrödinger Equations as Models of Superfluidity
Condensate models for superfluid helium II with nonlocal potentials are considered. The potentials are chosen so that the models give a good fit to the Landau dispersion curve; i.e., the plot of
Sculpting oscillators with light within a nonlinear quantum fluid
Polaritons—quasiparticles made up of a photon and exciton strongly coupled together—can form macroscopic quantum states even at room temperature. Now these so-called condensates are imaged directly.
Optical superfluid phase transitions and trapping of polariton condensates.
TLDR
This work directly image persistently circulating superfluid and shows how flows of light-matter quasiparticles are dominated by the quantum pressure in such configurable laser-written potential landscapes.
Spatial pattern formation and polarization dynamics of a nonequilibrium spinor polariton condensate
Quasiparticles in semiconductors—such as microcavity polaritons—can form condensates in which the steady-state density profile is set by the balance of pumping and decay. By taking account of the
Nontrivial phase coupling in polariton multiplets
